SPECIFICATION formingpart of Letters Patent No. 748,273, dated December29, 1903- Application filed May 9, 1903. SerialNo. 156,891. (No model.)

To a. whom it may concern:

Be it known that we, JOSEPH FRANK, residing in New York city, county and Stateof New York, and FREDERICK BENZ, J r., residing at Haledon, county of Passaic, and State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in Loom Shuttle-Motions; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to ribbon-looms of the type known to the trade as doubledecker looms-that is to say, looms in which the capacity is increased by providing for carrying'on the weaving in two or more superposed planes; and it consists in certain improvements having for their object to simplify and render more compact that portion of the mechanism of such looms which involves the batten and the part of the shuttlecontrolling means which is directly carried by the batten.

In the accompanying drawings, Figure 1 is a view in front elevation of the batten and the shuttles and their controlling means as constructed in accordance with the principles of this invention. Fig. 2 is a vertical sectional view taken on the line 00 w in Fig. 1, and Fig. 3 is an underneath view of the rack and of certain rollers detached on which said rack runs.

In the drawings, a designates the batten, and b a series of brackets which are secured to the back of the batten and are braced at the top by a strip 0.

d designates a horizontal cross-piece form-' ing a part of each bracket, and e designates horizontal projections extending laterally from each bracket at an elevation slightly higher than the cross-piece d.

The back upper edge of the batten is recessed opposite each bracket 19, so that thus is produced a series of sockets f,'in which the lower tier of reeds seat. The cross-piece d has its front face set back from the front face of the corresponding bracket b--that is to say, coincident with a dotted lineg in Fig. 2sufficiently, so that when the reed is seated in socket f it can stand vertically. The top of the reed may be secured against a crosspiece (1 by a screw it. The projections e are recessed, as at i, to receive the upper tier of reeds, which latter may be secured to the strip 0 by catches j.

Against the front faces of the several brackets b is secured a strip is. Above and below this strip are secured the shuttle-blocksl and m, corresponding to the upper and lowertiers of shuttles n and 0, respectively. The pinionsp for working the upper series of shuttles are arranged in the lower members of the upper set of shuttle-blocks, while the pinions q for the lower series of shuttles are arranged in the upper members of the lower set of.

blocks. Th us both sets of pinions are brought relatively close together.

Between the two sets of shuttle-blocks is arranged a single rack r, the same having its upper and lower surfaces formed with 'rows of teeth 5 s. The rack may be actuated by any of the well-known means. It is shod on both its top and bottom surfaces, on both sides of the rack-teeth formed therein, by metallic strips t, secured thereto by screws to. It is supported on the lower set of blocks by antifriction-rollers i), which are journaled on bearing-pins w, arranged in the lower set of blocks. Thus wear and tear is materially reduced and the action of the parts rendered considerably easier than would otherwise be the case.

The rack is guided true-that is to say, kept in proper position relatively to the strip lc-by plates on, which may be secured to the lower members of the upper set of shuttleblocks by screws y or in any other desired manner.

Upon viewing Fig. 3, it will be seen that the antifriction-rollers are arranged in staggered disposition. This arrangement insures bringing all the antifriction-rollers at all times into play and as a consequence a more true and even motion of the rack-bar.

Having thus fully described our invention,

'carried by the guiding means, each set of rollers engaging one of said strips on the under side of said rack and the rollers in one set being opposite spaces between those in the other, and two sets of pinions arranged in the guiding means, the one between the rack and the upper tier of shuttles and the other between the rack and the lower tier of 20 shuttles, substantially as described.

In testimony that We claim the foregoing we have hereunto set our hands this 24th day of April, 1903.
